Placebo administered daily for 8 weeks

Detailed Description:

This study would be the first prospective, placebo-controlled study to our knowledge of any pharmacotherapy strategy for the treatment of comorbid generalized anxiety (or any comorbid anxiety) in patients with bipolar disorder. Our hypotheses are:

  1. Ziprasidone flexibly dosed from 40 to 160 mg/day will reduce anxiety symptoms significantly more than placebo in patients with bipolar disorder who have a full or subsyndromal diagnosis of generalized anxiety disorder (GAD).
  2. Ziprasidone will be well tolerated in patients with generalized anxiety based on the incidence of treatment emergent adverse effects during 8 weeks of therapy, and based on a lack of worsening of bipolar depression, mania or hypomania compared to placebo.
  3. Treatment with ziprasidone will have a significantly greater positive impact on measures of quality of life and resilience than placebo.

Ages Eligible for Study:   18 Years to 75 Years

Inclusion Criteria:

  • Male and female outpatients, aged 18 to 75 years.
  • Diagnosis of Bipolar Disorder (Bipolar I or Bipolar II).
  • Current diagnosis of Generalized Anxiety Disorder (GAD).
  • Participants must be on at least one of the following mood stabilizers at steady dose for at least 4 weeks prior to randomization: lithium with blood levels between 0.4-1.4 meq/L, valproic acid/divalproate sodium (with levels between 50-150 ugm/dl) carbamazepine (blood levels between 4-12 mcg/ml), or lamotrigine (dosed 50-400 mg/day).

Exclusion Criteria:

  • Pregnant or lactating women or others not using acceptable means of birth control (e.g., IUD, oral contraceptives, barrier devices, condoms and foam, implanted progesterone rods stabilized for at least 3 months).

  • Current cognitive behavioral therapy directed toward the treatment of generalized anxiety disorder.
  • History of hypersensitivity to or lack of response to ziprasidone.
  • Concomitant treatment with other typical or atypical antipsychotics; patients should be off other typical or atypical antipsychotics for at least one week prior to study baseline.
  • Patients with significant suicidal ideation or who have enacted suicidal behaviors within 3 months prior to intake will be excluded from study participation and referred for appropriate clinical intervention.
  • Patients who have had a psychiatric hospitalization (including for bipolar disorder) in the past 3 months are excluded.
  • Seizure disorders with the exception of a history of febrile seizures if they occurred during childhood, were isolated, and did not recur in adulthood.
